Question

Hello here is what I want, I connect to a DB and retrieve the biggest element of the UniqueId column, and assign it to an integer variable named maxID, here is my approach:

int maxID = 0;
Statement s2 = con.createStatement();
s2.execute("SELECT MAX(UniqueId) FROM MyTable");    
ResultSet rs2 = s2.getResultSet(); // 
while ( rs2.next() ){
  maxID = rs2.getInt(0);
}

What would be a decent way of solving this, it feels like a very crude way by using “rs2.next()” while loop.

Thanks

Answer 1

if (rs2.next()) {
  maxID = rs2.getInt(1);
}
